Specification of To all 'whom 'it may conoenn: l Be it known that I, CHARLES V. Cofrfmw, a. citizen of the United State, residing' ati Sheridan, -in the County of La Salle and State of Illinois, have inventeil a new andi useful Combination vPontable Elevator and 'VagowDump, lo'frivliieh the following is all specification. g

My invention relates to eievatois for ele-2 vatin'g grain and a device for dumping wagons; the two apparatuses combined tol@ gether form a complete machine `or d ievloe,y for dumping ,grain from wagon and ele-l vating it; and the objects of my improve` int-nis are', iii-st, to provide means whereby; the elevator anni the wagon clump are driven i `the relative speed oi" the two can be changed g while in motion g second, to'malie e universal" i agen dumping device whieh is Capable of,v being placed in any position relative to the elevator third, to have the Wagon clump eonnetzteil to thesonice of power by a Strut` brace; touith, to provitie en adjustable re-1 oeiving' cnveyer; fifth, to malte a folding ieceiving conveyor; sixt-li, to makenn automatic folding elevator; seventh, to autonmtionily tighten anti loosen .the e-.levatmfv belt when the elevator extended and itol led; eighth, tomoiini a hydraulic jack or suitable device on the elevator tiue to operate the Wagon dump; ninth, to make `a novel consi'ufftion oi' truck foi' the elevator 'wliieh will automatically allow: the elevator boot to resi on the ground when the. eleven' tor is in a raieii position; tenth, to enable the Whole ileviee to he 'loaded on a wheeled truck and to be into operative position by one pei-son; eleventh, to make a simple, eheap and durable oonstxuetion and otherv obit-acts to become"apparent from the cie- Seription to follow. j

As is well `known in the art, nA Wagon (lump and an elevatol are operated together ns a Complete iilevice for conveying' grain from a wagon to a grain loin oi' corn ei'ib.

by suitable mechanism, to (lump the grain out at the tail endo-f the wagon-into a le# eeivingnr conveyor, 'from whence it is' Icone. veyed into the elevator boot and thnee'ear- Heretofove motivepower has heel applietb EATOR WGON-DUBIR Letterhient- Patented Ust'. T2 1.913. Renewed February 15, i913. Seal No. MSAESL l wagon has to be drawn into position with" its reai" end just above lthe receiving conveyer and its front Wheels in positionto beelevated by the Wagon dump device. Here totore this positioning of the Wagon Was aceompliehed either, by driving the Wagon onto a. turn-table immediately in front ot the receiving conveyer and then turning the wagon on a pivot through an are of ninety degrees, or, by first swinging the reeeivine' eonveyer about a pivot outy of thepath o? the wagon and after the wagen is in position returning the eonveyer to a position dii'eotly under the rear end of the Wagon; 'these methods. are v'both 'very inconvenient and i.' .finire a considerable amount of muscular' energy.

. For

dump is driven by the same motor which runs the eievator and iscapnble of having the use of `my inventionthe Wagon its speed of operation elia-neatly@ slower or faster, desired, while elevatorcontinues" to travel,continuously at 'the same rate ot' speed; and to permit placing' the mig-on in proper position, the receiving,r Conveyoi" has a pivotefl section whichl is simpl litteil to a vei'tieal position to allovvv 'the wagon'to pass by, and vis then again loweifed to the ground. It is often'desii'able to 'hm-'e the Wagon in different positions .relative to the elevator at dillereut buildings or in (lilei'ent localities about the saine building, anil my iin'e'ntion makes it possible to arrange the receivingconveyor and Wagon (lmnp in any position abouttheelevator.

. r;l`he wagon: dumping device or lifting derrivlc is devoid of all shafts and vgear wheels, so as to be light enough for'n single person to handle; the lifting power'is transmitted to it through a single cable or chain :from a lifting device. Thisv cable or chain is carried alongfon a, jointed strut brace which permits the wagon dump to be placed in any position. The receiving conveyor is made with the flipper 01 hopper part sliduble longitudinally so es to enable moving 'to run the elevator and' hand powei- ,was an i it to a 'position dimdlly under the wagen vating purposes.

box in case the Wagon has through` carelessness been placed slightly to one side or the other. The elevator is made of a plurality of sections jointed together and. is provided at each joint with a sheave over' which passes a cable, by means otivhich 'the sev! eral sections are folded on ea'ch other or extended, vas desired, by manipulating the cables. When the elevator is folded, some provision must be .made for slackening -the conveying beltand this I accomplish by providing an -automatic looseningv and tightening device.

It is verydesirableto have the wagon dumping'device as light in weight-as possible, since this part of the apparatus must be handled each time the elevatorv is set up at or removed from a given location. To accomplish this desired result I mount the power or lifting inechanisnn-.which 1n this case is a hydraulic cylinder or jack, on the truck when it` is folded for transportation,

and is similarly automatically dismounted from the front truck with the elevator boot restingy on the ground when set up for ele- This result is obtained by a novel vconnection between the elevator and truck to be described. y

It will be understood that in illustrating and describing my invention complete de-` vice is shown to illustrate one construction embodying the new and novel features of my invention,l and that numerous 'changes may be made in different parts of the ma. chine without in the least departing from.

the spirit of the invention.

'Ilo describe my invention 'so versed in the art to which it make and use the same, I have illustrated it on the 'accompanying five sheets of draw! y ings forming a partv of thissliecication, in which: 4 i

is the wagon dumping dei-rick, 18 is the jointed strut brace connecting the derrick 17 to the frame of the hydraulic jack 19. The wagon frame 20 is mounted onl the front truck 21 and rear truck 22. The elevator 23 is pivotally mounted on the front endof the wagon frame 20 and is supportedf'in its raised position by the masts 24 which are pivotally attached to the rear end .of the wagon frame 20. 25 is the receiving conveyer operatively connected to the lower end of the elevator 23. The derrick 17 may be of any desired construction so longl as it 'vertical position to permit the passage of a serves as a means for attaching' a rope, cable,

Achain or b ar in such manner that one end of a Wagon can be lifted by exerting a pull on As an illu'ssaid rope, cable chain or rod. tration, I have shown a cable 26 connected to two cables 27 and 28 which latter pass f over small sheaves or idlers 29 and '3.0 in such position that the free ends of the cables 27 and 28 will hang down one on either side of a wagon placed under the dei-rick 17 as shown in Figs. 2 and 3, the position of the Wagon being shown by dotted ,lines in Fig. 3.

The free ends of the cables '27 and 28, are provided with'loo s 3l which are placed over loi the extending en s of the two front wheel hubs, and are prevented from slipping olf `of the same by the hooks 32 secured to the cables 27 .and 28 each offsaid hooks .being hookedaround a spoke of the wheel.- The free end 'of the cable. 26 has preferably attached thereto a short piece of chain' 33, and a hook 34 which is secured `tothe end of cable 35 is'hooked into any desired lilik of the chain 33 tos ttlie proper adjustment.

lThe-strut brace 18-may be of any desired construction, the essential features of it being to serve as a spanner to hold any two ear 40 mounted on the derrick 17. A" pin is passed through the perforations in the ears 39'and 40 which connects lthem pivotally. The ear V10 being pivoted to the derrick 17 arid also pivoted to the ears 39 forms practi- -eally a universal jointv between the strut brace 18 and the derrick 17. 'A roller or idler il is mounted on the "Free end of the member SZand another idler 42 is mounted on the pivot 38. The idler 4l, isV mounted -on the member 3T by nieans of a removable sleeve, which serves to ineke the idler '4l ldistance beyond the cndsvo'f tlie strut brace 18, the hooks 34- and 11G.

The shaft 53 is provided witlifan ceceiilr'ic (Sl which is Connected by a; pitmaii rod G2 to tie leien rod ol' a pump 64. The outlet ofthe pump 64 is connected to one end of the cylinder G5 of the jack 19'. Within the cylinder (35 is provided the usual` piston which is secured to the rod G6 piercing the remainingr endl of the cylinder 65. Secured to the exposed end of rod 66 is the end piece 67, to whiclris -ser-V eiired one or more rods (S8 which have their remaining end secured lo a sliding piece (39, which is conveniently. but not necessarily made in the shape of a ring to slide on the eyli. der a guide. rfhe sliding piece (3f) is provided. with means to which the hook 4G yabove referred to can he fastened;

From the `deseription'thus far' givenl it is clear that the rotation ot shaft 5? will operate pump (S4- which will lorf'e the piston v rod lill out and pull the sliding piece l!) along on cylinder (35 in such manner as to cause a pull on the cabler 5, which in turn transmits the pull to cables 27 and 2 8 which li't't the Wagon attached 4thereto.

lt is preferable to use a liquidwhich will not freeze in the pump (lil. The. inlet/of pump (S4 is connected by a pipe 7() to the end ot' cylinder (35' remote troni the pump (i4,-

The upper end of the neck 75 which -lies in a horizontal plane is swivelly connected to a bracket 76 rigidly secured to the elevator Q3 in such manner that the lower end of the neck 75 and the hopper portion 74 can be placed in any position radially about said swivel connection. Mounted on the bracket. 70 is a shaft 77 which has secured to one end the sprocket wheel 78 which is connected by a chain to the sprocket wheel 59 referred to above. The chain v58 is conveniently run over the three sprocket wheels 78, 59 and 57` and the chaintightening idlerv 79 is mounted on the elevator 23 to bea'r against said chain 58. l

.n endlessconveyer belt 80 (sec Figs. 8 to 12), travels over wheels mounted on sha i' t 8l jo'urnaled in the upper horizontal end of the. neck 75. The shaft 81 has secured to one-end the sprocket wheel 82 which is con- `nected by chain 83 to sprocket 81 Jmounted .on shaft 85 also journaledrin, the upper horizontal end of neck 75. The Ashafts 85 and 77 are'operatimyi connected by the usual train of' gearsounted on the swivel connection referredto above.v

' ThehopperJ-.pqrtion 74 is pivotally, con'- nected tothe eckportion 't' 5 at 86 which is l made in thevform of a hinge extending the entire' width of the elevator onr the line of the floor of the upper inclinedy chute thus permittin the hopper portion v74 to be rom its horizontal position about the pivot 8 6 until it reaches the position shown in Fig. 8. The two side wings 87 and 88 are pivotally secured to the rods 89 and .90 which are slidably-mounted on the base or return chute 91. The pivoting of the wings 87 and 88 permits either wing tobe swung down and out into the position shown Figs. "11 and 12, so as to extend partly ilnder the lrear end of the wagon and pre- `vent any lf lfrain from falling outside of the hopper. The longitudinal movcmentof the I rods 89 and 90 permit the longitudinal Inovement of the hopper wings 89 and 8,8, so that these can be moved to a position directly under the rear end of the wagon, in case theV wa gon has carelessly been drawn shghtly' toeither side of the properposition; -i

block .or gate 92 is'bolted 1n position to the 1 front end of the wing which is swung under the wagon to prevent the grain from spilling out on the ground. The rear end of both wings 87 and 8S are provided with permanent endpieces 93 to prevent the grain f-rom'spilling" ontothe ground. The rods 89 and are preferably lnade rigid to the end piece 91 forming the cud ot the hopper, and the front ends of said rods are rigidly connected `together by the inverted U shaped standard or brace 95, which tits zontal position.

The front truck Q1 is providedwith thello'b ordinary fifth-wheel 103 'and is connected to the wagon'Ql) in a novel manner. The upper structure of the lift-h wheel. 103 is provi-ded with the cross bars or holsters 104 and 105 extending across the entire width of the elevator Q8. A shaft 106 extends'across on the under side of the elevator 23 and fixed to Asaid elevator by passing through t-wo lugs 107 shown by dotted lines in Fig. 9; this shaft 10G also passesthrough two lugs 108 formed on either end of the bar4 104.y and through two bearing blocks 109 l rigidlyvsecured to the wagon Q0, thus the upper portion of fifth wheel 103, the clevator i113 and the wagon 20 are connected together by the shaft 106 which act-s as a pivotal point about which they swing. The

other bar 105 on the fifth wheel 103 has.

long lugs 110 froined one on each end thereol which titloosely against the sides of the elevator 23, are curved on an arc about the shaft 106 as a cent-er and are provided with the vslots 111 into which fit the pins 112 rigidly secured to the elevator 23.

From the description thus far given it incense will be-'seen that the elevator 23 can be ,liftedor turned: upward in an arc about the` shaft lOfiasv a pivot, until the lower end of the elevatorstrikes the ground at which vtime the lWeight of the elevatoris transl mound the truck 21 will, partly by forcel of gravity ande partly by the tendency of the elevator to slide back on the ground, be swnng about the shaft 106 as av pivot away from. the elevatorA 23 until said truck is barely supported on the ground and the pins 112. are in the endsof slots .111 remote from the fifth wheelil. This is espeorally true when .the elevator, boot rests lower than the truck. The positionof the pins 112Y and,y the length of the slots 111 de-y termine the extent of the arc-nate movement of the truck '21 aboutthe shaft 106. The idlers 56 and 57 above referred to are conveniently but not necessarily pivotally mounted on shaft- 106.- y

sha-ft 60 inthe lower end of the elevator carries the Wheels which drive the endless belt conveyer to be described and to provide a means of access to these working parts, the elevator case is made with a removable section 113 secured at 114: and also fastened at 115.

The mastsv 24 at their lower ends are rigidly fastened to the rear axle '116,'and a shortdistance above thisv they arepivotally secured to the 'Wagon 20 at 117. A windI lass 118 is fixed to4 the lower end' of the masts 241,'spanning'tl1e space between-the masts, upon Whichis Wound the ropes or cables -J119 which' pass from the Windlass 118 upward 'over the idlers 120`at the top of the masts 211;,"tbenc'edown and secured tel the elevator 23 at 121. The relative position ot these several fastenings are such that, if a pull is exerted on cables 119 by operating the windlass 1187 while the parts are in a folded position asiseen in' F 1g. 1, the

masts 251 `will rst be raised 'to the position.

shown in Fig. 2, and a further operation of the winrhass 118 will lift the elevator 23 about .its pivot, theshaft 10G, into the position shown in Fig. 2. As a matter of fact, the ,masts 2e actually move to'a vertical position before the elevator y23 starts to lift, and to prevent the masts 211 lfrom fallingy overltoclivfard l provide the guy ropes haviiig one end secured to the front end ot' the wagon' 20 and the remaining end of euch rope seeuredifto the masts 2li by n'ieans of thelcgs or standards 123 which as seen .in Fig. 1, rests on brackets 124 secured to the wagon 20 when in its folded position. "l'he lower ends ofthe standards 123l as i the brackets 124- are provided' with perH lo. .tions which register when the masts idly secnred. to the section 127.

are in a folded position, and into which is placedv a'bolt or pin to prevent the accidental displacement of the standards 123 dtiringv transgjiortation. The purpose ot providirngr the standards for the masts is to c hang the derrick 17 thereon as seen in l l4 1. l

1he elevator 23 comprises the -four sections 125,126, 127 and 128 which are hinged together at 1251", 130 and 131. ed.. they forni a straight line elevator as seen in Fig. 2. i

together at 129, at which point the grooved lllhen extcnd- Sections and 126 are hinged wheels 132, one on either side of the elevator, e

are rigidly secured to the section 126. Sections 126 and 127,' are hinged together at 13G, at which point the grooved wheels 133, 1

one on either side oit the elevator, are rigf and 128 are hinged together at 131 at which point the grooved wheels 134, one on either side of the elevator are rigidly secured to the section 128. Cables 135 extend around ythe grooved wheels 13e and from thence through. guides on Wheels 133 end 132 and finally around small sprocket wheels '136, mounted one on either side of section 125,

Sections 12T the cables 135 at this place being a sprocket chain. The sprocket wheelsl 136 are rotated by some self-locking hand power means as a worm and gear 137. The cables 135 are v.secured against slippage on the Wheels 134 by any means of clamping. 'When the sprocket Wheels 186 are rotated non-clocltv wise viewed in'Fig. 2, the cables .135 Will canse the wheels 1341 to be rotated in the vsaine direction and since the section 128 of the elevator is rigidly secured tothe Wheels 134 it will also be turned aboutthe hinge 131 as a pivot until it is folded back onto the section 127 oi the elevator.

again swing the section 128 of the elevator out into its extended position as seen in Fig. 2. ,It is obvious `that the purposeof mounting the wheels 136 and worms 137 on section 125 to bring'the operating crank A reverse' 4rotation ot'- the sprocket .wheels 136 will Within easy reach of a person operating the same. The Worms 137 or an equivalent could bearranged to engage the wheels 134 and have the means ot' operating it extend along on the elevator to Within easy reach of a ,persoin without going beyond the.

boundsof the appended claims. Another pair of cables 138 one on either side ofthe elevator are passed around the grooved 'Wheels 133, Ito which they are securely clamped and thence are passed `idly past but lyingv in they grooves of the Wheels .132 and thence to and around the sprocket Wheels 139, mounted on section of the elevator,Y the cables 138' at this portion` being,r chalns, The sprocket Wheels 139 are rotated by some selloclinf hand` power means a i 'When the sprocket worm and gear 140.

ias

the wheels 133 in the same direction and since the section 127 of the elevator 1s r1gidly secured to the wheels 1.33 it -Will be swung about the hinge 130 as a pivot until the end 141 of section 128 (said section 128 having-previously been folded down upon section 127) contacts with section 126. The further rotation of sprocket wheels 139 will by means of cables 138 and force of gravity, cause the section 126 to swing about hinge 129 as a pivot until the -section 128 comes to rest on section 125 as seen in Fig. -1. n The reverse movement of sprocket wheels i139 will by means of cables 138 first swing section 126 about pivot 129 until said section is in a position to form a straight line continuation of section 125, and then swing section 127 about pivot 130 until said4 section is in a straight'line with sections 125 and 126 as seen in Fig. 2. A small idler 142 is provided on each wheel 132 to prevent the cables 138 from leaving the grooves of wheels 132 when the elevator is in a' folded-position.

-An endless belt conveyer 143, see Figs. 14 to, 16, passes up in the upper chute of the elevator 23 and down in the return chute of the same and is arranged to travel around wheels on drive shaft 59 and over Wheels on shaft 144 mounted in the upper end of section 128. Since both strands of the endless belt conveyer 143 are on the same side of all the hinges of the elevator it is necessary to make some provision to slacken said,

belt conveyer 143 when folding the elevator,

land I have made such provision by an automatically operated device.

That is the shaft 144 is automatically moved in a direct-ion away from the end 141 when the section 128 is swung about pivot 131 from the position shown `in dotted lines in Fig. 13, -to the full line position in said Fig. 13. The shaft 144 is mounted in the bearing plates 145 rigidlv secured to the outer sides of the box like frame 146 which is mounted to slide between the bottom of 'the return chute and the bottoln of the upper chute of the elevator. As shown in the drawings the box like frame v146 is confined within the sides of the return chute but has its sides fitting snugly against-l the outer surfaces of the upper chute of the elevator, thus preventing any possible leakage of grain at this point. To rigidly secure the return chute and the upper chute together the bent braces 147 are provided on either side. l

The box like' frame 146 is held in position longitudinally by the two side bars 148 each of which have one end pivoted to frame 146 at 149 and the remaining end pivoted to the arm 150 which are loosely pivoted concentric with the hinge 131. Adjustable set screws 151 are provided in suitable lugs on section 127 of the elevator which serve fas stops for the arms 150', As seen in Fig.

13, whenv the section 128 is in its 'extended' position, 2'. e. in a straight line with section 127 as indicated by dotted lines, the arms 150 are resting against the set screw 1 51 and by means of the bars 148 the box like frame146 and therefore the shaft 144, are

able taking up the slack in the belt 143 occasioned by Wear the set screws 151 are made adjustable. It is also seen in Fig. 13, that when section 128 is moved from its extended position to a partly folded position, as the full line position the frame 146 is permitted to move in a direction away from the l end 141 thus slackening the belt 143. The up er side 152 of the frame 146 is made of Woof and is covered with sheet metal 153 which is bent in a cylindrical form about the sha-ft 144l and its extremity turned and secured to the under side of tbe wood board 152. The metal covering 153 serves as an extension of the bottom of the upper chute and also prevents any grain from falling any place besides out at the discharge end ofI the elevator'.r

As seen in Fig. 1, the complete apparatus is conveniently folded on the Wagon in a compact form. The main upright frames of the derrickv 17 are hung on the hooks 154 provided on the masts 24.
